Of course, the best way to go big is with portal axles. That gives you back the gear ratio (perhaps even a bit more), gives you massively more ground clearance and doesn't affect suspension geometry...

In Holland Wouter can get you / us VOLVO Portals .. which they deem the ULTIMATE best .. with the axles .. never asked the price [he used it in his truck when he did the SILKY WAY Ralley [WOUTER O being the previous previous previous owner of LOBO [Then "Witblitz"]

Don't bring God down to your level of faith ... bring your faith up to His level!
